FIRE ALARM AND EXTINGUISHER.

Application filed November 21. 1907.

.vide an apparatus of this character which may be readily and cheaply installed in public buildings, residences and like places and which will simultaneously alarm occupants in the buildings and extinguish the fire.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the spe cific structure shown and described may be made within the scope of the claims without de arting from the spirit of the invention.

11 the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a sectional view of a portion of a building showing my improved fire alarm and extinguisher installed therein,

Fig. 2 is a horizontal sectional view on the line 22 of Fi 1, Fig. 3 is a side elevational view of the va ve and its operatin mechanism showing the valve m a close position,

Fig. 4 is a similar view showin the valve in an open OSItlOIl, Flg. 5 1s a side elevatlonal view of t e alarm mechanism, Fig ois avertical longitudinal sectional view therethrough.

Referring now, more particularly to the drawings, there is shown a portion of a build roved fire extinguisher and alarm is installecl In the drawings, there is shown a water supply pi e lO'which is preferably located beneath t e ceiling and adjacent the walls of rooms, hallways or the like, and connected to this water-pipe, there are shown valves 1 1. These valves 11 are provided with vertically disposed valve stems 12, to which are ivotallymounted operating le vers 13. The evers 13 are also pivoted at one end as shown at 14 to posts 15 which are carried by each valve 11. The valves 11 are connected to discharge pipes 16 and these pipes are preferably arranged at the ceilings of- 'a room as shown. The ipes 16 are provided with upwardly exten ding posts 17, and ivotal y mounted to each of these posts 't ere are shown levers 18. The levers 18 are arranged- Specification of Letters Patent.

to extend over one end of each lever 13 of the valve stems 11 for holding the valves in a closed position normally. The posts 17 are provided with stop's 19 which are arrangedio limit theupward movement of the levers l8.

Adjacent the valves 11, there are shown non-conducting blocks 20, and these blocks are provided with a hollow portion 21 which opens outwardly of the block at one end and which terminates at its opposite end within a point of the opposite end of the block.

This arrangement is such that a portion of the block is enlarged as shown at 22 and in this enlargement there is formed alongitudinally disposed passage 23. A plunger rod 24 is disposed with a portion in the passage 23 and a portion within the hollow portion 21 of the block, as shown. The rod 24 is provided with a plunger head 25 which is disposed within the portion 21 of-the block, and arranged between the enlargement 22 and the inner face of the-plunger 25 there is shown a coil spring 26'. The blocks 20 are each provided with a contact piece 27, and this contact piece is arranged with a )ortion within the hollow portion 21 of the blocks 20. Each contact-piece 27 is provided with a transverse in 28, and this pin has ortions 29 and 30 disposed in passages 32 w iich are formed in the walls of the block 20. The.

contact piece 27 is connected by a wire 33 to.

a battery 34 which may be located at a convenient point in the building or outside thereof it found desirable, and this battery is connected by way of a wire 35 to a bell 36 or other suitable alarm. The plunger rod 24is provided with jam nuts 37 between which there is secured a wire 38 which also leads to the battery 34. A cord 39 has one of its ends attached to the plunger rod 24 and this cord is arranged in a suitable manner around the room of the building, and this cord thus serves to hold the plunger head 25 out of engagement with the contact 27. The other end of the cord is thus arranged to hold the lever with one end engaged above one end of the lever 13 whereby the valves 11 are held in a closed position. The pi es 16 are perforated as shown at 16 and )y means of these perforations it will be seen that water may be forced through the same when the valves 11 are in an open position.

Upon burning of a building, the flames of a fire travel upwardly and toward the ceiling, and when the flames come in contact with the cord 39, the cord will of course be be sounded. The cord 39 will 01" course reevers for the valves, means engaged with closed, non-conductive blocks, a plunger slidable within each block, a contact -p1ece carried by each block, an electrical source, connections between the contact and the burned,'and the plunger rod 24 will thus be released to cause the plunger head 25 to contact With the piece 27 and the alarm will thus lease the lever 13 also and the water which is admitted to the valves 11 under pressure will 0 en the valves and the water will thus be discharged from the perforations 16 which are formed in the pipes 16.

' What is claimed'is: Thevcombination with Water distributing ipes including valves therefor, operating nections between each plunger and the bell,

plunger and each lever respectively.

In testimony whereof I affix my signature, in presence of two Witnesses. CLARK WILSON.
